Abstract
The invention discloses a current selection pass control assembly which comprises a current sensor connected with a circuit conductor, an electromagnet movable iron core and an electromagnet coil. The current selection pass control assembly is characterized by being provided with a filter, one end of the filter is connected with the current sensor, and the other end of the filter is connected with the electromagnet iron core through a signal wire. The filter is a high-flux filter or low-flux filter, and the low-flux filter is a special ceramic filter or an RC (Resistor/Capacitor) assembly or comprises a 1/4 wavelength wire. The invention has the beneficial effects that the current selection pass control assembly is arranged in the circuit, the filter filters a current signal passing through the circuit and enables the current signal not to be expected to be sent to the electromagnet coil, the electromagnet movable iron core rapidly acts to impact a mechanical tripping mechanism for disconnecting the circuit, so that the purpose of protecting electrical equipment is achieved.
Description
Technical field
The present invention relates to a kind of control assembly, particularly a kind of electric current is selected to pass through control assembly.
Background technology
Electric current useless in circuit can cause damage to electric equipment products, in the circuit being mixed with electromagnetic pulse electric current, lightning current, power current, direct current, some electric equipment products can only allow power current or direct current passes through, have only allow lightning current, electromagnetic pulse passes through.When only need lightning current and electromagnetic pulse electric current by time, AC and DC electric current is by causing damage even initiation fire to electric equipment; When only need AC and DC by time, lightning current and electromagnetic pulse electric current will to cause damage even initiation fire to electric equipment.Due to the restriction of acceptor sum through-current capability; filter can't be used merely at present to complete this task, therefore need to carry out extraction processing, when useless dangerous currents is passed through to useless dangerous currents signal; cut off current path by motion, reach protection object.
Summary of the invention
Object of the present invention, be to provide a kind of electric current to select by control assembly, sensor installation in circuit, delivers to the signal of collection in filter and is separated.After needing the dangerous currents signal abandoned to be separated, deliver to electromagnetic mechanism by circuit disjunction, reach the object of protection electric equipment.This method proves through Product Validation, can thoroughly cut off unwanted dangerous currents.
The present invention realizes like this, described a kind of electric current is selected to pass through control assembly, it comprises the current sensor, the electromagnet that are connected with circuit conductor and moves iron core, electromagnet coil, it is characterized in that: have a filter, its one end is connected with current sensor, and its other end is connected with electromagnet coil through holding wire.
Filter of the present invention or be high pass filter or for low pass filter; Low pass filter or for dedicated ceramic filter or be RC assembly or be made up of 1/4 wavelength line.
The invention has the beneficial effects as follows; be provided with electric current in circuit and select logical control assembly; filter leaches does not wish that the current signal that circuit passes through gives electromagnet coil, and electromagnet moves the rapid action of iron core and clashes into mechanical trip mechanism open circuit, reaches the object of protection electric equipment.

Fig. 2 is fundamental diagram of the present invention;
Fig. 3 is that the present invention leaches AC signal to tripping mechanism schematic diagram.
In Fig. 1: 1. current sensor, 2. filter, 3. holding wire, 4. electromagnet is dynamic unshakable in one's determination, 5. electromagnet coil, 6. circuit conductor.
In Fig. 3: 7. lightning current, 8. power current, 9. filter, 10. power current, 11. electromagnet.
Embodiment
A kind of electric current of the present invention is selected to pass through control assembly, as shown in Figure 1, 2, 3, it comprises the current sensor 1, the electromagnet that are connected with circuit conductor 6 and moves iron core 4, electromagnet coil 5, there is a filter 2, its one end is connected with current sensor 1, and its other end is connected with electromagnet coil 5 through holding wire 3.
Filter of the present invention or be high pass filter or for low pass filter; Low pass filter or for dedicated ceramic filter or be RC assembly or be made up of 1/4 wavelength line.Electromagnet is polarized electromagnet or claims polarized relay, comprises electromagnet and moves iron core and electromagnet coil.
Circuit only allow electromagnetic pulse, lightning current by time, its course of work: as shown in Figure 1, 2, 3.
Current sensor 1 on conductor 6 detects that different current signal gives filter 2; filter 2 gives electromagnet after being leached by power current; electromagnet moves core 4 unshakable in one's determination action shock mechanical trip mechanism open circuit rapidly; namely circuit is only disconnected after the incipient stage have passed very little power current, reaches the effect of protection electric equipment.In the event of electromagnetic pulse or lightning current in circuit, traffic filter blocks signal to be passed through, and electromagnet is failure to actuate.Direct benefit of the present invention be when do not need certain electric current by time, in circuit collection signal, filtering, once there is unwanted electric current open circuit immediately in circuit, protection electric equipment safe and reliable.
In Fig. 2: electromagnet D, coil L, low pass filter LPF, transducer CT.
Lightning current 7 is indicated, power current 8, filter 9, power current 10, electromagnet 11 in Fig. 3.
